Evaluation of Anogenital Distance and Anti-Müllerian Hormone Plasmatic Concentration as Potential Phenotypes to Predict Reproductive Performance in Holstein Heifers

Veterinary Sciences
Anogenital distance (AGD) is a marker of the degree of prenatal exposure to androgens in multiple species, and it has been suggested that there is an inverse association between AGD and fertility.

Effects of Prepartum Supplementation and Yeast Fermentation Products on the Progesterone‐Modulated Transfer of Passive Immunity in Bos indicus Cows

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Inadequate colostrum intake increases risks of calf morbidity and mortality. This study investigated the effects of prepartum and early postpartum supplementation and yeast fermentation products on late‐pregnant Bos indicus cows, and the role of progesterone in mediating passive immunity transfer.

Gestational Feed Restriction Induces Differential Expression of Novel Long Non‐Coding RNAs in Offspring Skeletal Muscle

Animal Genetics, Volume 57, Issue 4, August 2026.
ABSTRACT This study aimed to investigate how maternal feed restriction at different gestational stages alters the expression of novel long non‐coding RNAs (lncRNAs) in the skeletal muscle of goat offspring. LncRNAs are emerging as important regulators of biological processes, including myogenesis, yet their role in fetal programming remains largely ...
